Description

支援增強上鏈(EU)傳輸的無線傳輸/接收單元及方法Wireless transmission/reception unit and method supporting enhanced uplink (EU) transmission

本發明是關於在無線通訊系統中運作之混合自動重複請求(H－ARQ)，該系統包含至少一無線傳輸/接收單元(WTRU)、至少一節點B以及一無線網路控制器(RNC)。本發明尤其是關於一種動態分配在WTRU中之H－ARQ程序之方法和系統，以支援增強上鏈(EU)傳輸。The present invention relates to hybrid automatic repeat request (H-ARQ) operating in a wireless communication system, the system comprising at least one wireless transmit/receive unit (WTRU), at least one Node B, and a Radio Network Controller (RNC). More particularly, the present invention relates to a method and system for dynamically allocating H-ARQ procedures in a WTRU to support enhanced uplink (EU) transmission.

EU運作會減少上鏈等待時間，改善生產率，且提供實體無線資源更有效的使用。在EU運作期間，會使用H－ARQ程序以支援介於一WTRU及u節點B之間的EU傳輸，其中包含一回饋程序的幫助，以報告該EU資料傳輸是成功或是不成功。The EU operation will reduce the waiting time of the chain, improve productivity, and provide more efficient use of physical wireless resources. During EU operation, the H-ARQ procedure is used to support EU transmissions between a WTRU and a Node B, including the help of a feedback procedure to report whether the EU data transmission was successful or unsuccessful.

為了每一WTRU，會定義一些H－ARQ程序，且每一WTRU同時支援多種H－ARQ程序。由於與UL傳輸時間相較之下，每一EU資料傳輸之回饋循環相對較長，且可能需要不同數量的傳輸以成功傳輸每一EU傳輸，因此需要一WTRU同時操作數個H－ARQ程序，以增加資料率並且減少等待時間。For each WTRU, some H-ARQ procedures are defined, and each WTRU supports multiple H-ARQ procedures simultaneously. Since the feedback loop for each EU data transmission is relatively long compared to the UL transmission time, and a different number of transmissions may be required to successfully transmit each EU transmission, a WTRU is required to simultaneously operate several H-ARQ procedures. To increase the data rate and reduce waiting time.

在何一個WTRU連結方面，會存在多種邏輯頻道，這些邏輯頻道具有不同的生產率、等待時間、錯誤率以及服務品質(QoS)需求。為了滿足這些需求，該RNC為每一邏輯頻道設定優先權，極為已知的媒體存取控制(MAC)邏輯頻道優先權(MLP)，MLP係被映至一專用頻道MAC(MAC－d)流，其係連接至該EU MAC(MAC－e)，其管理該EUH－ARQ程序。In terms of which WTRU connection, there are multiple logical channels with different productivity, latency, error rate, and quality of service (QoS) requirements. To meet these needs, the RNC sets priorities for each logical channel, the extremely known Media Access Control (MAC) logical channel priority (MLP), and the MLP is mapped to a dedicated channel MAC (MAC-d) stream. It is connected to the EU MAC (MAC-e), which manages the EUH-ARQ procedure.

在下鏈(DL)頻道中高速下鏈封包存取(HSDPA)方面存在有類似的設計，當高優先權資料需要傳輸，且所有的H－ARQ程序都已經分配給較佳低優先權資料傳輸時，便允許較高優先權傳輸佔用較低優先權之H－ARQ傳輸，當佔用發生時，較低優先權資料會在重新排定在稍晚的時間進行H－ARQ傳輸。A similar design exists for high-speed downlink packet access (HSDPA) in the downlink (DL) channel, when high-priority data needs to be transmitted, and all H-ARQ programs have been allocated for better low-priority data transmission. The higher priority transmission allows for lower priority H-ARQ transmissions, and when the occupancy occurs, the lower priority data is rescheduled for H-ARQ transmission at a later time.

H－ARQ程序佔用的問題在於會損失組合的好處。EUH－ARQ運作的一個重要優點便在於儲存來自先前傳輸所接收資料，且結合先前傳輸與接續傳輸已經增加成功資料傳輸之可靠性的能力。然而，當H－ARQ程序被佔用時，所儲存先前傳輸之資料以及組合的優勢便會因此喪失。The problem with the H-ARQ program is that it loses the benefits of the combination. An important advantage of EUH-ARQ operation is the ability to store data received from previous transmissions, and combined with previous transmissions and subsequent transmissions, has increased the reliability of successful data transmission. However, when the H-ARQ program is occupied, the advantages of storing previously transmitted data and combinations are thus lost.

執行H－ARQ程序佔用之其中一個理由，是因為在WTRU中能配置的H－ARQ程序數量是受限的，每一H－ARQ程序需要大量的記憶體供接收程序使用，而在WTRU中記憶體的數量是有限的。One of the reasons for performing H-ARQ procedures is because the number of H-ARQ programs that can be configured in the WTRU is limited. Each H-ARQ program requires a large amount of memory for the receiving program to use, and the WTRU remembers The number of bodies is limited.

因為通常會有大量的低優先權資料而具有少量的高優先權資料，當處理低優先權傳輸時，便必須避免封鎖高優先權資料傳輸，以便維持較高優先權資料Qos需求，如果較低優先權資料壟斷H－ARQ程序，則會降低整體的系統效能，除此之外，因為低優先權資料允許較大的等待時間，其將會導致較大的H－ARQ程序把持時間。Since there is usually a large amount of low priority data with a small amount of high priority data, when dealing with low priority transmissions, it is necessary to avoid blocking high priority data transmission in order to maintain the higher priority data Qos demand, if lower The monopoly of the H-ARQ program on the priority data will reduce the overall system performance. In addition, because the low priority data allows for a larger wait time, it will result in a larger H-ARQ program holding time.

H－ARQ程序佔用可解決傳輸優先權的問題，但代價就是組合優勢的喪失，且相對地，會造成較低的無線資源使用效率。當因為較不健全的調變和編碼機制(MCS)造成較少實體資源可被使用，使得較大百分比的第一或可能第二傳輸失敗時，便會期待在 H－ARQ系統中達成最佳整體效能。在本例中，當執行H－ARQ程序佔用時，這些初始傳輸和重新傳輸將會頻繁地被重複以達成成功傳輸，其會浪費資源用以傳輸初始被佔用的資源。The H-ARQ program occupies the problem of solving the transmission priority, but the cost is the loss of the combined advantage, and relatively, the lower the efficiency of the use of the radio resources. When less physical resources can be used because of the less robust modulation and coding mechanism (MCS), a larger percentage of the first or possible second transmissions will fail, The best overall performance is achieved in the H-ARQ system. In this example, when H-ARQ program occupancy is performed, these initial transmissions and retransmissions will be frequently repeated to achieve a successful transmission, which would waste resources to transmit the initially occupied resources.

本發明是一種用以動態分配在WTRU中之H－ARQ程序之方法和裝置，以支援EU傳輸。在WTRU中之H－ARQ程序係為了特定傳輸頻道(TrCHs)、專用頻道媒體存取控制(MAC－d)流或是不同資料傳輸優先權等級之邏輯頻道所保留，該WTRU從這些保留H－ARQ程序中分配可用的H－ARQ程序，選擇性地，可允許一較高優先權頻道分配保留給較低優先權頻道之H－ARQ程序，較低優先權H－ARQ程序可被佔用。該佔用可受到資料傳輸緊急(舉例來說，接近使用期限計時器之期滿時間)，或是RNC之H－ARQ程序組態所限制。或者，可配置一H－ARQ程序之共享池，且可依據每一頻道之優先權，從該共享池中配置H－ARQ程序，且較低優先權之H－ARQ程序可被佔用。The present invention is a method and apparatus for dynamically allocating H-ARQ procedures in a WTRU to support EU transmission. The H-ARQ procedures in the WTRU are reserved for specific transport channels (TrCHs), dedicated channel media access control (MAC-d) streams, or logical channels of different data transmission priority levels from which the WTRU reserves H- The available H-ARQ program is allocated in the ARQ program, and optionally, a higher priority channel can be assigned to the H-ARQ program reserved for the lower priority channel, and the lower priority H-ARQ program can be occupied. This occupancy may be limited by data transmission emergency (for example, near the expiration time of the lifespan timer) or by the RNC's H-ARQ program configuration. Alternatively, a shared pool of H-ARQ programs can be configured, and the H-ARQ program can be configured from the shared pool according to the priority of each channel, and the lower priority H-ARQ program can be occupied.

根據本發明，較低優先權資料可達成一最大資料率，且較高優先權傳輸可於任何時間開始，而不需要請求H－ARQ程序佔用。藉由保留H－ARQ程序給特定的頻道且允許WTRU動態地分配這些H－ARQ程序，這些頻道的EU資料率及傳輸等待時間能更佳地確保達到其QoS需求。In accordance with the present invention, lower priority data can achieve a maximum data rate, and higher priority transmissions can begin at any time without requiring H-ARQ program occupancy. By preserving the H-ARQ procedure for a particular channel and allowing the WTRU to dynamically allocate these H-ARQ procedures, the EU data rate and transmission latency of these channels can better ensure that their QoS requirements are met.

此後，專用術語「WTRU」包含但並未限制於一使用者設備(UE)、一行動台、一固定或行動用戶單元、一呼叫器或可在一無 線環境下操作之任何形式之裝置。當本文此後提到專用術語「節點B」，其包含但並未限制於一基地台、一站台控制器、一存取點或是在無線環境下任何結識的介面裝置。Hereinafter, the specific term "WTRU" includes but is not limited to a user equipment (UE), a mobile station, a fixed or mobile subscriber unit, a pager or may be in a Any form of device that operates in a line environment. The term "Node B" is used hereinafter to include, but is not limited to, a base station, a station controller, an access point, or any interface device that is acquainted with the wireless environment.

本發明之特徵可整合至一積體電路(IC)，或是配置在包含許多相互連接元件之電路上。Features of the invention may be integrated into an integrated circuit (IC) or on a circuit comprising a plurality of interconnected components.

第1圖所示為根據本發明之無線通訊系統100運作方塊圖，該系統100包含至少一WTRU 102、至少一節點B104以及一RNC 106。該RMC 106經由一Iub/Iur 112配置該節點B 104及該WTRU 102之EU參數以控制整體EU運作，例如在WTRU 102中H－ARQ程序124之組態、初始傳輸功率等級、最大允許EU傳輸功率、或是可用實體資源。一UL EU頻道108係建立於該WTRU 102及該節點B 104之間，以便幫助EU傳輸，該UL EU傳輸108包含一增強專用頻道(E－DCH)用於E－DCH資料傳輸，且亦可包含一分離的UL EU信號發送頻道，該UL EU信號亦可經由該E－DCH傳輸。1 is a block diagram showing the operation of a wireless communication system 100 in accordance with the present invention. The system 100 includes at least one WTRU 102, at least one Node B 104, and an RNC 106. The RMC 106 configures the Node B 104 and the EU parameters of the WTRU 102 via an Iub/Iur 112 to control overall EU operation, such as configuration of the H-ARQ program 124 in the WTRU 102, initial transmission power level, maximum allowed EU transmission. Power, or available physical resources. A UL EU channel 108 is established between the WTRU 102 and the Node B 104 to facilitate EU transmission. The UL EU transmission 108 includes an Enhanced Dedicated Channel (E-DCH) for E-DCH data transmission, and may also A separate UL EU signal transmission channel is included, and the UL EU signal can also be transmitted via the E-DCH.

該WTRU 102包含一控制器122、複數個H－ARQ程序124、一記憶體126、以及一傳輸器/接收器128。該控制器122控制整體H－ARQ分派及E－DCH傳輸程序，除此之外，該控制器122保持追蹤H－ARQ程序之每一傳輸狀態。該記憶體126儲存傳輸之E－DCH資料，該H－ARQ程序124及該記憶體126可分割以支援複數個優先權資料等級，這將在下文中更詳細的描述。The WTRU 102 includes a controller 122, a plurality of H-ARQ programs 124, a memory 126, and a transmitter/receiver 128. The controller 122 controls the overall H-ARQ assignment and E-DCH transmission procedures, in addition to which the controller 122 keeps track of each transmission state of the H-ARQ program. The memory 126 stores the transmitted E-DCH data, and the H-ARQ program 124 and the memory 126 are partitioned to support a plurality of priority data levels, as will be described in more detail below.

在E－DCH傳輸方面，該WTRU 102經由該UL EU頻道108送出一頻道分配請求給該節點B，在回應方面，該節點B 104經由DL EU信號發送頻道110送出頻道分配資訊給該WTRU 102。 在EU實體資源分配給該WTRU 102之後，該WTRU 102經由該UL EU頻道108傳輸該E－DCH資料。該節點B會經由該DLEU信號發送頻道110送出H－ARQ運作之一確認(ACK)或非確認(NACK)訊息。In terms of E-DCH transmission, the WTRU 102 sends a channel allocation request to the Node B via the UL EU channel 108, and in response, the Node B 104 sends channel allocation information to the WTRU 102 via the DL EU signaling channel 110. After the EU entity resource is allocated to the WTRU 102, the WTRU 102 transmits the E-DCH material via the UL EU channel 108. The Node B sends an acknowledgement (ACK) or non-acknowledgement (NACK) message to the H-ARQ operation via the DLEU signal transmission channel 110.

H－ARQ運作之記憶體需求對接收器來說是個主要的問題。在HSDPA方面，H－ARQ程序之數量及保留給每一H－ARQ程序的記憶體都降到最低。在EU方面，在WTRU中的記憶體需求並沒有像HSDPA如此限制，其係最大資料率限制該H－ARQ程序及該記憶體需求之最低量。對每一個「停止並等待」的H－ARQ程序傳輸來說，會有一個產生該傳輸且等待和處理該傳輸之回饋的循環，為了具備持續傳輸的能力，數個H－ARQ程序便需要依序列操作。The memory requirements of H-ARQ operation are a major problem for the receiver. In terms of HSDPA, the number of H-ARQ programs and the memory reserved for each H-ARQ program are minimized. On the EU side, the memory requirements in the WTRU are not as limited as HSDPA, which is the maximum data rate that limits the minimum amount of H-ARQ procedures and memory requirements. For each "stop and wait" H-ARQ program transmission, there will be a loop that generates the transmission and waits for and processes the feedback of the transmission. In order to have the capability of continuous transmission, several H-ARQ programs need to rely on Sequence operation.

由於我們在EU中並不關注該WTRU 102之記憶體需求，因此H－ARQ程序124的數量及保留給每一優先權等級之記憶體126，便可超過達成每一優先權等級之特定資料率所需要的H－ARQ程序數量。該WTRU 102能在一時間配置比所使用還要多的H－ARQ程序，依據本發明之一實施方式，該H－ARQ程序係保留給特定TrCHs、MAC－d流或是邏輯頻道，其係能由該WTRU 102於任何時間動態地配置，便可避免已經分配的H－ARQ程序的佔用以及相對的組合優勢的喪失。Since we are not concerned with the memory requirements of the WTRU 102 in the EU, the number of H-ARQ programs 124 and the memory 126 reserved for each priority level can exceed the specific data rate for each priority level. The number of H-ARQ programs required. The WTRU 102 can configure more H-ARQ procedures than used at a time. According to an embodiment of the present invention, the H-ARQ procedure is reserved for a particular TrCHs, MAC-d flows, or logical channels. The WTRU 102 can be dynamically configured at any time to avoid the occupation of the already allocated H-ARQ procedures and the loss of relative combined advantages.

在該WTRU 102及該節點B 104之間的該H－ARQ運作可為同步化或是非同步化。在非同步化的H－ARQ運作方面，用以選擇在該WTRU 102之H－ARQ程序之機制，並不會由節點B 104所知悉，因此該H－ARQ程序應可在每一傳輸中識別。在同步化 的H－ARQ運作方面，用以選擇在該WTRU 102之H－ARQ程序之機制，不但是預設好的且節點B 104亦知悉。該節點B 104可是別在該WTRU 102所使用的H－ARQ程序，且其係基於預設的傳輸排程。每一E－DCH傳輸包含一新資料指示器(NDI)，以指示該傳輸是「新傳輸」或是「重新傳輸」，該NDI之初始值指示該傳輸係為「新傳輸」每一H－ARQ傳輸的重新傳輸序列號碼也可提供類似的資訊。在同步化H－ARQ運作中，該節點B 104可判定哪一個H－ARQ程序在該WTRU 102中使用，且可判定哪一個傳輸應該與先前傳輸組合，其係基於該傳輸何時被送出。The H-ARQ operation between the WTRU 102 and the Node B 104 can be either synchronized or unsynchronized. In terms of non-synchronized H-ARQ operation, the mechanism for selecting the H-ARQ procedure at the WTRU 102 is not known by the Node B 104, so the H-ARQ procedure should be identifiable in each transmission. . Synchronization In terms of H-ARQ operation, the mechanism for selecting the H-ARQ procedure at the WTRU 102 is not only pre-set but also known to Node B 104. The Node B 104 may be an H-ARQ program that is used by the WTRU 102 and is based on a preset transmission schedule. Each E-DCH transmission includes a new data indicator (NDI) to indicate whether the transmission is "new transmission" or "retransmission". The initial value of the NDI indicates that the transmission system is "new transmission" for each H- The retransmission sequence number of the ARQ transmission can also provide similar information. In synchronized H-ARQ operation, the Node B 104 can determine which H-ARQ procedure is used in the WTRU 102 and can determine which transmission should be combined with the previous transmission based on when the transmission was sent.

第2圖所示為用以分配在WTRU 102中之H－ARQ程序124之程序200流程圖，其係根據本發明之第一實施方式。該RNC106配置該WTRU 102之組態，例如配置與每一邏輯頻道、MAC－d流、傳輸頻道(TrCH)有關之H－ARQ程序124及/或記憶體分割，或是資料優先權。這較佳地是透過第E層的無線資源控制(RRC)信號發送程序所執行。2 is a flow diagram of a procedure 200 for assigning an H-ARQ program 124 in a WTRU 102 in accordance with a first embodiment of the present invention. The RNC 106 configures the configuration of the WTRU 102, such as configuring H-ARQ procedures 124 and/or memory partitioning, or data priority, associated with each logical channel, MAC-d flow, transmission channel (TrCH). This is preferably performed by the Radio Resource Control (RRC) signaling procedure of Layer E.

在每一傳輸時間間隙方面，在步驟204中，該WTRU 102可動態地分配關於被服務的TrCH、MAC－d流或是邏輯頻道之一H－ARQ程序。該WTRU 102判定該實體資源是否已經由該節點B 104所配置(步驟206)，如果該實體資源尚未配置，則該程序200回到步驟204以等待下一個TTI，如果實體資源已經被配置，則該WTRU 102便由該最高優先權等級中選擇資料以便在現行TTi傳輸(步驟208)。該WTRU 102決定哪一個資料使用所選的H－ARQ程序124傳輸，在此例中，每一次分派一個新的H－ARQ程序時，在最高優先權中的資料都會優於在較低優先權等級的資 料傳輸。In terms of each transmission time slot, in step 204, the WTRU 102 can dynamically allocate an H-ARQ procedure with respect to one of the served TrCH, MAC-d flows, or logical channels. The WTRU 102 determines if the physical resource has been configured by the Node B 104 (step 206), and if the physical resource has not been configured, the process 200 returns to step 204 to wait for the next TTI, if the physical resource has been configured, then The WTRU 102 selects data from the highest priority level for transmission at the current TTi (step 208). The WTRU 102 determines which data to transmit using the selected H-ARQ procedure 124. In this example, each time a new H-ARQ procedure is dispatched, the data in the highest priority is better than the lower priority. Grade of capital Material transfer.

如果沒有資料等候傳輸，則程序200便會回到步驟204等待下一次TTI，如果有要傳輸資料，且在步驟208中選擇了最高優先權等級之資料，則該WTRU 102會判定一H－ARQ程序124是否已經分派給其他具有「未成功傳輸」狀態之資料(步驟210)。如果一H－ARQ程序124已經分配其他未成功傳輸之資料(亦即收到包含NACK訊習知回饋資訊)，且並未在等待資料回饋訊息，則在步驟212便會選擇關於此優先權等級最早分派之H－ARQ程序，且該H－ARQ程序會於現行TTI中傳輸(步驟214)。該最早分派之H－ARQ程序可由最低傳輸序列號碼(TSN)，或是相對於分派在同一優先權資料中其他的H－ARQ程序重新傳輸的最高號碼所決定。If there is no data waiting for transmission, then the process 200 will return to step 204 to wait for the next TTI. If there is data to be transmitted and the highest priority level of data is selected in step 208, the WTRU 102 will determine an H-ARQ. Whether the program 124 has been dispatched to other materials having an "unsuccessful transfer" status (step 210). If an H-ARQ program 124 has assigned other unsuccessfully transmitted data (ie, received NACK message feedback information) and is not waiting for a data feedback message, then at step 212, a priority level is selected. The H-ARQ program is assigned the earliest, and the H-ARQ procedure is transmitted in the current TTI (step 214). The earliest assigned H-ARQ procedure may be determined by the lowest transmission sequence number (TSN) or the highest number retransmitted relative to other H-ARQ procedures assigned in the same priority material.

如果目前沒有H－ARQ程序分派給其他具有「未成功傳輸」狀態之資料，則該WTRU 102便判定是否有關於TrCH、MAC－d流或邏輯頻道之H－ARQ程序，可供支援在此優先權等級資料之傳輸(步驟216)。如果有可用的H－ARQ程序，則該WTRU 102便分配一個關於所選資料之優先權等級的保留H－ARQ程序124(步驟218)，該優先權等級可映象以配置關於至少一邏輯頻道、一MAC－d流及一TrCH其中之一的H－ARQ程序。如果沒有所選資料之TrCH、MAC－d流或是邏輯頻道無可用的H－ARQ程序，則該優先權會在現行TTI中標記為被封鎖(步驟220)。程序200接著回到步驟208選擇下一個最高優先權資料，關於該TrCH、MAC－d流或是邏輯頻道以支援較低優先權等級之H－ARQ程序，會等待下一次TTI，其中實體資源會被配置且所有未完成等待傳輸較高 優先權的H－ARQ程序將會被服務。If there is currently no H-ARQ procedure assigned to other data with an "unsuccessful transmission" status, the WTRU 102 determines if there is an H-ARQ procedure for the TrCH, MAC-d flow or logical channel, for which support is prioritized. Transmission of the rights level data (step 216). If there is an available H-ARQ procedure, the WTRU 102 assigns a reserved H-ARQ procedure 124 (step 218) regarding the priority level of the selected material, the priority level being mapable to configure for at least one logical channel. An H-ARQ program of one of a MAC-d stream and a TrCH. If there is no H-ARQ program available for the TrCH, MAC-d stream or logical channel of the selected data, then the priority is marked as blocked in the current TTI (step 220). The program 200 then returns to step 208 to select the next highest priority material. The H-ARQ program for the TrCH, MAC-d flow or logical channel to support the lower priority level will wait for the next TTI, where the physical resource will Configured and all pending completion transfers are higher The priority H-ARQ program will be served.

必須要限制達成每一邏輯頻道、MAC－d流或是TrCH之最大資料率所需的H－ARQ數量，該RNC 106可限制保留給至少邏輯頻道、MAC－d流及TrCH其中之一的H－ARQ程序的最大量，當較低優先權H－ARQ程序已經分派時，這可有效地限制每一邏輯頻道、MAC－d流或TrCH的最大資料率，高優先權資料具有一限制數量的H－ARQ程序，其限制最大資料率，但仍可提供低傳輸等待時間。舉例來說，信號發送無線承載(SRBs)壅塞的(道中需要低等待時間，而不是高資料率，該SRB TrCH、MAC－d流或是邏輯頻道接著可由具有較高優先權RRC程序之RNC所配置，且此頻道會有一或多個專用的H－ARQ程序。The number of H-ARQs required to achieve the maximum data rate for each logical channel, MAC-d flow, or TrCH must be limited, and the RNC 106 can limit the H reserved to at least one of the logical channel, the MAC-d flow, and the TrCH. - the maximum amount of ARQ program, which effectively limits the maximum data rate per logical channel, MAC-d flow or TrCH when the lower priority H-ARQ procedure has been dispatched, the high priority data has a limited number of H-ARQ program, which limits the maximum data rate, but still provides low transmission latency. For example, signalling radio bearers (SRBs) are blocked (in the channel, low latency is required instead of high data rate, and the SRB TrCH, MAC-d flow or logical channel can then be used by the RNC with a higher priority RRC procedure. Configured, and this channel will have one or more dedicated H-ARQ programs.

第3圖所示為用以分配在WTRU 102中之H－ARQ程序之程序300流程圖，其係根據本發明之第二實施方式。該RNC 106配置該WTRU 102之組態，舉例來說，配置關於每一邏輯頻道、MAC－d流、TrCH之H－ARQ程序數量及/或記憶體分割，或是資料優先權等級(步驟302)，這較佳地係透過RRC程序執行。3 is a flow diagram of a routine 300 for distributing H-ARQ procedures in the WTRU 102 in accordance with a second embodiment of the present invention. The RNC 106 configures the configuration of the WTRU 102, for example, configuring the number of H-ARQ procedures and/or memory partitioning, or data priority level for each logical channel, MAC-d flow, TrCH (step 302). ), which is preferably performed by the RRC procedure.

在每一傳輸時間間隙方面，在步驟304中，該WTRU 102可動態地分配H－ARQ程序。該WTRU 102判定該實體資源是否已經由該節點B 104所配置(步驟306)，如果該實體資源尚未配置，則該程序300回到步驟304以等待下一個TTI，如果實體資源已經被配置，則當每一次新的H－ARQ程序被分派時，該WTRU 102便決定在現行TTI中所傳輸的最高優先權資料(步驟308)。In terms of each transmission time gap, in step 304, the WTRU 102 can dynamically allocate an H-ARQ procedure. The WTRU 102 determines if the physical resource has been configured by the Node B 104 (step 306), and if the physical resource has not been configured, the process 300 returns to step 304 to wait for the next TTI, if the physical resource has been configured, then When each new H-ARQ procedure is dispatched, the WTRU 102 determines the highest priority data transmitted in the active TTI (step 308).

如果沒有資料等候傳輸，則程序300便會回到步驟304等待下一次TTI，如果有要傳輸資料，該WTRU 102會判定一H－ARQ 程序是否已經分派給其他具有「未成功傳輸」狀態之資料(步驟310)。如果一H－ARQ程序已經分配給其他未成功傳輸之最高優先權資料(亦即收到包含NACK訊習知回饋資訊)，且並未在等待資料回饋訊息，則在步驟312便會選擇關於此優先權等級最早分派之H－ARQ程序，且該H－ARQ程序會於現行TTI中傳輸(步驟314)。If there is no data waiting for transmission, then the process 300 will return to step 304 to await the next TTI. If there is data to be transmitted, the WTRU 102 will determine an H-ARQ. Whether the program has been dispatched to other materials having an "unsuccessful transfer" status (step 310). If an H-ARQ procedure has been assigned to other top priority data that was not successfully transmitted (ie, received NACK message feedback information) and is not waiting for a data feedback message, then at step 312, a message is selected. The priority level is assigned to the H-ARQ program, and the H-ARQ procedure is transmitted in the current TTI (step 314).

如果目前沒有H－ARQ程序分派給最高優先權資料，則該WTRU 102便判定是否有關於此優先權等級之TrCH、MAC－d流或邏輯頻道之H－ARQ程序(步驟316)。如果有可用的所選資料之優先權等級之H－ARQ程序，則該WTRU 102便分配一個此優先權等級的保留H－ARQ程序(步驟318)，且該H－ARQ程序係於步驟314中傳輸。If no H-ARQ procedure is currently assigned to the highest priority profile, the WTRU 102 determines whether the H-ARQ procedure for the TrCH, MAC-d flow or logical channel of this priority level is involved (step 316). If there is an H-ARQ procedure for the priority level of the selected data available, the WTRU 102 assigns a reserved H-ARQ procedure of this priority level (step 318), and the H-ARQ procedure is in step 314. transmission.

如果所有資料之優先權等級沒有可用的H－ARQ程序，則該WTRU 102便判定是否有是否有較低優先權等級之H－ARQ程序可用(步驟320)。如果有較低優先權等級之H－ARQ程序，則程序300便進入步驟318已分配該較低優先權等級之H－ARQ程序，且該分配之H－ARQ程序會被傳輸(步驟314)。如果在步驟320中，判定沒有較低優先權等級之H－ARQ程序可用，則此優先權等級將於現行TTI中封鎖(步驟322)，且程序300會回到步驟308以選擇下一個最高優先權資料。If there is no available H-ARQ procedure for the priority level of all data, the WTRU 102 determines if there is a lower priority level H-ARQ procedure available (step 320). If there is a lower priority level H-ARQ procedure, then routine 300 proceeds to step 318 where the lower priority level H-ARQ procedure has been assigned and the assigned H-ARQ procedure is transmitted (step 314). If, in step 320, it is determined that an H-ARQ procedure without a lower priority level is available, then the priority level will be blocked in the current TTI (step 322), and the routine 300 will return to step 308 to select the next highest priority. Right information.

選擇性地，如果沒有較低優先權等級之H－ARQ程序可用，則可佔用配置給較低優先權等級之H－ARQ程序。該RNC 106配置保留給每一優先權等級之H－ARQ數量，如果保留給較高優先權資料之H－ARQ程序數量較多，則佔用會較少發生，如果保留 給較高優先權資料之H－ARQ程序數量較少，則會有較多的佔用發生。Alternatively, if a lower priority level H-ARQ procedure is available, the H-ARQ procedure configured for a lower priority level may be occupied. The RNC 106 configures the number of H-ARQs reserved for each priority level. If the number of H-ARQ procedures reserved for higher priority data is larger, the occupation will occur less if retained. If the number of H-ARQ programs for higher priority data is small, more occupancy will occur.

第4圖所示為用以分配在WTRU 102中之H－ARQ程序之程序400流程圖，其係根據本發明之第E實施方式。該RNC 106H－ARQ程序之一共同池，超過H－ARQ程序最大量之數量可於任何時間由該WTRU 102所使用(步驟402)。4 is a flow diagram of a procedure 400 for allocating H-ARQ procedures in the WTRU 102 in accordance with an Eth embodiment of the present invention. The pool of one of the RNC 106H-ARQ procedures, the maximum amount exceeding the H-ARQ procedure, can be used by the WTRU 102 at any time (step 402).

在每一傳輸時間間隙方面，該WTRU 102動態地分配H－ARQ程序。該WTRU 102判定該實體資源是否已經由該節點B 104所配置(步驟406)，如果該實體資源尚未配置，則該程序400回到步驟404以等待下一個TTI，如果實體資源已經被配置，則當每一次新的H－ARQ程序被分派時，該WTRU 102便決定在最高優先權中之資料以在現行TTI中傳輸(步驟408)。The WTRU 102 dynamically allocates H-ARQ procedures in terms of each transmission time gap. The WTRU 102 determines if the entity resource has been configured by the Node B 104 (step 406), and if the entity resource has not been configured, the process 400 returns to step 404 to wait for the next TTI, if the entity resource has been configured, then When each new H-ARQ procedure is dispatched, the WTRU 102 determines the data in the highest priority for transmission in the active TTI (step 408).

如果沒有資料等候傳輸，則程序400便會回到步驟404等待下一次TTI，如果有要傳輸資料，該WTRU 102會判定一H－ARQ程序是否已經分派給其他具有「未成功傳輸」狀態之最高優先權資料(步驟410)。如果一H－ARQ程序已經分配給其他未成功傳輸之最高優先權資料(亦即收到NACK回饋狀態)，且並未在等待資料回饋訊息，則在步驟412便會選擇關於此優先權等級最早分派之H－ARQ程序，且該H－ARQ程序會於現行TTI中傳輸(步驟414)。If there is no data waiting for transmission, then the process 400 will return to step 404 to await the next TTI. If there is data to be transmitted, the WTRU 102 will determine if an H-ARQ procedure has been assigned to the other highest with an "unsuccessful transmission" status. Priority information (step 410). If an H-ARQ procedure has been assigned to the other highest priority data that was not successfully transmitted (ie, received a NACK feedback status) and is not waiting for a data feedback message, then at step 412, the priority level is selected at the earliest. The H-ARQ procedure is dispatched and the H-ARQ procedure is transmitted in the current TTI (step 414).

如果目前沒有H－ARQ程序分派給其他最高優先權資料，則該WTRU 102便判定是否有可用之H－ARQ程序(步驟416)。如果有可用的H－ARQ程序，則該WTRU 102便分配一個H－ARQ程序(步驟418)，且該分派之H－ARQ程序係於步驟414中傳輸。If no H-ARQ procedure is currently assigned to other highest priority data, the WTRU 102 determines if there is an available H-ARQ procedure (step 416). If there is an available H-ARQ procedure, the WTRU 102 assigns an H-ARQ procedure (step 418) and the assigned H-ARQ procedure is transmitted in step 414.

如果在步驟416中，判定沒有可用的H－ARQ程序，則該 WTRU 102便判定是否有是否有已經分配給較低優先權等級資料之H－ARQ程序(步驟420)。如果有已經分配給較低優先權等級資料之H－ARQ程序，則分配給最低優先權等級資料之H－ARQ程序可被佔用(步驟422)，該被佔用的H－ARQ程序係分配給所選資料，且該分配H－ARQ程序係被傳輸(步驟418、414)，如果沒有已經分昢給較低優先權資料之H－ARQ程序，則該優先權等級便會在現行TTI中被封鎖，且該程序400會回到步驟408以選擇係一個最高優先權資料。If, in step 416, it is determined that no H-ARQ program is available, then The WTRU 102 determines if there is an H-ARQ procedure that has been assigned to the lower priority level profile (step 420). If there is an H-ARQ program that has been assigned to a lower priority level profile, the H-ARQ program assigned to the lowest priority level profile can be occupied (step 422), and the occupied H-ARQ program is assigned to the The data is selected and the assigned H-ARQ procedure is transmitted (steps 418, 414). If there is no H-ARQ procedure that has been assigned to lower priority data, the priority level is blocked in the current TTI. And the program 400 will return to step 408 to select a highest priority profile.
